The Umba is a river in northeast Tanzania in the Tanga region .

course

It rises in the Schageiu forest (Shagayu) in the West Usambara Mountains at an altitude of 2,000 m and flows eastwards on the northern side of the mountain range. The Mbalamu, which comes from the extreme north of the Usambara Mountains, and the Mglumi flow into the Umba at Lelwa. Shortly before it flows into the Indian Ocean , the Umba crosses the border into Kenya . The estuary itself marks the easternmost point of the border between Tanzania and Kenya, from which it was drawn in a largely straight line to the northwest in the 19th century towards Lake Victoria .

resources

In the mid-1960s, rich deposits of precious stones (especially sapphires and Spessartines ) were discovered on the upper reaches of the river . Also on the river is the Umba River Game Reserve , a game reserve that, together with the Mkomazi Reserve, covers approx. 2600 km² .

Hydrometry

Like most rivers in the region, the Umba flows depending on the rainy season. Average monthly flow through the Umba measured at the hydrological station at Mbuta, about 40 km above the mouth in m³ / s (1963–2003).
